Description

The FA N7930C is an active pow er factor correction

(PFC) controller for boost PFC applications that operate

in critical conduction mode ( CRM). It uses a voltage-

mode PWM that compares an internal ramp signal w ith

the error amplifier output to generate a MOSFET turn-off

signal. Because the voltage- mode CRM PFC controller

does not need rectified A C line voltage infor mation, it

saves the pow er loss of an input voltage-sensing netw ork

necessary for a current-mode CRM PFC controller.

FA N7930C provides over-voltage protection (OV P),

open-feedback

protection,

over-current

protection

(OCP),

input-voltage-absent

detection,

and

under-

voltage lockout protection ( UVLO). The PFC-ready pin

can be used to trigger other pow er stages w hen PFC

output voltage reaches the proper level w ith hysteresis.

The FAN7930C can be disabled if the INV pin voltage is

low er than 0.45 V and the operating current decreases

to a very low level. Us ing a new variable on-time control

method, total har monic distortion (THD) is low er than in

conventional CRM boost PFC ICs.
